The Dancing On Ice host made sure she was dressed to impress for Sunday night's show.
Ahead of kickstarting the live event, the blonde offered a sneak peek of her outfit on her Holly Willoughby Instagram profile.
Looking every inch the bombshell, the 36-year-old rocked a slashed dress, which featured a daring high slit.
In keeping with this week's "Disco" theme, the starlet's outfit was adorned with sequins.

Busting a move as she modelled the attire, Holly served major legs appeal as she flashed her toned pins to the masses.
Despite filming next to an ice rink, Willoughby resisted the urge to add another layer of clothing.
She completed the jaw-dropping look with a killer pair of metallic high heels and lashings of confidence.
Captioning the post, the mum-of-three wrote: "D-I-S-C-O... let's do this."
